Improvement in steam-lubricators

IMPROVEMENT IN STEAM-LUBRlCATORS.

The Scheule referred to in these Letters Patent and making part of the same.

To all 'whom fit may concern.:

Be it known that I, DANIEL Comme, oi Bellevile,

Sh Clair county, State ot' Illiuois,`l have invented a new and useful imru'ovcd Oil-Cup, of which the following is a full, clear, and exact description, reference heilig had tothe annexed drawing making part of this specitication, and representing a side elevation of same, with a portieri in section.

My invention is an improvement ou the oil-cup for which 'l made application for Letters Patent on the 22d day of April, A. D. 18H), lwhich application was allowed on the 27th day of May, A. D. 1811); and the object I have in view is todo away with the spring and lever attached to the piston-rod in that apparatus tor the purpose of counter-balancing the pressure of -the steam on the top of the piston.

The cup A is constructed in the same way, having an escape-pipe, s, and supply-pipe t, with acup, n., on its extremity.

It has the same tube G leading from near its top down to and connecting with the standard H, this latter being perforated by-a tube,'h, which opens into the bottom ofv the oil-cup, and is opened and closed b v thecock N, which also, as in the otherx apparatus, affords a vent te ai'i'oth'er tube7 not shown, leading from the bottom ofthe cup, for the purpose of allowing the steam in the cup to escape when the piston is forced down, so that the eup may receive a new supply of oil.

'lhe piston-rod B passes through a steam-tight stufing-,boxg (l, and has attached to its upper end a funnel-shaped cup, 1.

The rod is hollow, and its tubeo opens atone end into the cup A, below the piston C, and at the other into the cup l), thus allowing the steam entering the cup A. to act upon both the under side ot' the piston and also upon the interior ofl the cup I). rlhis7 as is evident, gives to the steam a much greater surface to act upon in its upward movement than it can possibly have when acting in the opposite direc-tion, land therefore the pressure of any steam upon the top of the piston will be more thanVcounterbalanced by the pressure on the under side of the piston and on the cup P, thus insuring a continual upward movement of the piston without the interposition of any springs or levers as counterpoises, as required in the former apparatus invented by me.

The funnel-shape ofthe cup l) lessens greatly, and downward pressure ofthe steam entering it, thelubriL eating substance is fed through the tube t, and then the steam being turned on by the cock N, the oil or other lubricating substance passes down the tube G, as in the former apparatus invented by'me.

vThat I claim as my invention, and desire to secure by Letters Patent, isl 1. The combination of the cup A piston C, hollow piston-rod B, and cup P, as and for the purpose shown and specified.

2. Theoombination of the cups A and I), piston C, hollow piston-rod B; and tubes Gr and 71 as and for the purpose shown and specified.
